[R] Histograms with bin proportions on the y-axis

[R. Michael Weylandt]

To open a graphics device, you usually use a function like png() or
eps() then do your plotting then dev.off() to close it when you're
done.

Sounds like you need something like hist(x, breaks = 100, freq = TRUE)

Hope that helps,

Michael
